How to solve this Bond with Geometrically Growing Coupons question

Setup

Setup

Let q be the yield per half-year and index the thirty coupon dates by k.

q=0.0622=0.031q=\frac{0.062}{2}=0.031
Ck=R(1.01)k1C_k=R(1.01)^{k-1}

The coupon coefficient is 21.9350891 and the redemption present value is 400.1659.

R=2,895.28400.165921.9350891=113.7499R=\frac{2{,}895.28-400.1659}{21.9350891}=113.7499

Answer

Answer

The first coupon rounds to 114, which is choice B.

R114(B)\boxed{R\approx114\quad\text{(B)}}
